I am emigrating to the USA from the UK and need to purchase a flight. I have noticed that direct one way flights are over £1000 and return flights are only just over £500. Is there any way to get the price for a return ticket for a one way? If not, are there any repercussions for not using the return flight? I have a visa and everything is above board, I just don't want to spend the £500 extra when I can just buy a return for half the price of a direct one way.
